Integrated Relay for Wireless Backhaul Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing bandwidth demand and coverage requirements in wireless networks, particularly in high-density areas like airports and shopping malls, are not adequately met by existing wireless communication systems, leading to congestion and suboptimal data throughput.
Innovation Solution
The implementation of integrated WiFi Relay (iWRELAY) techniques, which facilitate spectrum sharing by establishing wireless backhaul connections among multiple wireless access services using a relay device that communicates with wireless stations via one air interface protocol and an access point via a different protocol, improving radio link coverage and reducing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing wireless communication systems are used to meet increasing bandwidth demand and coverage requirements, then the system capacity and coverage should improve, but congestion increases and data throughput becomes suboptimal
Solution Approach 1:
The patent introduces a relay device as an intermediary between wireless stations and the access point. This relay device establishes separate wireless links with both the stations and the access point, creating an intermediate communication path that bypasses the congested direct links and improves overall network throughput and coverage.
2Adaptability or versatility
If multiple wireless access services share the same wireless medium, then spectrum utilization improves, but interference and congestion increase
Solution Approach 1:
The patent segments the wireless communication into separate links: one link between the relay device and wireless stations, and another link between the relay device and the access point. This segmentation allows different protocols and communication methods to be used on each link, reducing interference while maintaining spectrum sharing capabilities.
3Reliability
If wireless stations establish direct links with the access point, then communication reliability improves, but coverage area is limited
Solution Approach 1:
The patent extends the coverage area by introducing a spatial dimension through the relay device. Instead of all stations connecting directly to the access point in a single dimension, the relay device creates an extended communication path that reaches stations in areas that would otherwise be outside the access point's direct coverage range.

AI summary
A wireless communication system comprising a plurality of wireless stations communicating using a first air interface protocol a relay device, and an access point, wherein the plurality of wireless stations communicate with entities in a wide area network via the access point without establishing a direct wireless link with the access point, and wherein the relay device communicates with the plurality of wireless stations using the first air interface protocol and communicates with the access point using a second, different, wireless communication protocol. The second communication protocol, e.g., could be a backhaul protocol that is used by the access point to communicate with other access points in the system.
